Question

Plz help me i stuck in this

Answer 1

Solution: Arrange numbers in ascending order

Write CF distribution

x--------f--------cf

2--------13--------13

3--------7--------20

5--------8--------28

6--------9--------37

7--------12--------49

9--------14--------63

10--------11--------74

Total frequency(number) = 74=> even

Median is average of
$\frac{n}{2}, \bigg(\frac{n}{2} +1 \bigg)th$

$\frac{74}{2} = 37$
and 38 term

37 term of the distribution=6(check from CF)

38 term =7


$Median = \frac{6 + 7}{2} \\ \\ = \frac{13}{2} \\ \\ = 6.5$

Hope it helps you
